PNEUMATIC STRAW-STACKER.

SPECIFIGATIQN forming part of Letters Patent No. 672,732, dated April23, 1901 i LApplioation filed May 3, 1900. Serial No. 15.378. (Nomodel.)

To aZZwhom it may concern.-

Be it known that I, GEORGE F. CoNNnR, a V

citizen of the United States, residing at Port Huron, inthe county ofSt. Clair and State of Michigan, have invented certain new and useful Improvements in Pneu matic Straw-Stackers; andI do declare the followingto be a full,

clear, andexact description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use the same.

The invention relates to pneumatic strawstackers, and more particularlyto the manher of mounting the deflecting-hood on the outer end of thestacker-tube.

In the construction of pneumatic strawstackers it is common toprovidethe stackertube at its outer end with a deflecting-hood,

. either made of sliding sections or in one piece,

length of the stacker-tube to discharge the straw at different points.In someinstances the hood is provided with a sleeve which snugly fitsthe outer end of the stacker-tube,

and in other instances the sleeve and stackertube are provided with acoacting track-frame and rollers, the one carried by the stackertube andthe other by the sleeve of the hood. Both of these constructions areobjectionable and have serious disadvantages. In the first place, wherethe sleeve of the hood snugly fits the outer end of the stacker-tube toturn with respect to the same the parts are very apt to bind, due to theformation of rust when the machine is left standing unused betweenharvesting seasons, or this binding may result from the denti'ng of oneof the parts in the rough usage of the machine. The provision of theroller-frame is objectionable for the reason that it not only addsmaterially-increased'expense in the manufacture of the stacker,butadditional weight at a point where I it is desirable to have as littleweight as poscrease the weight of the parts at that point,

while at the same time the hood may have a free rotary movement withrespect to said tube struction and combination of parts, which will behereinafter fully described and claimed.

In the drawings, Figure 1 is a side elevation of the outer end of astacker-tube and the deflecting-hood secured thereto. Fig. 2 is a topplan view; and Fig. 3 is a vertical sectional view through the outer endof the stacker-tube and the hood-sleeve, showing theantifriction-rollers mounted between the two.

Referring to said drawings, 1 denotes the outer end of the stacker-tube,2 the deflecting-hood, and 3 the hood-sleeve. The sleeve and the tubeare formed with annular coinciding grooves 4 and 5, the one beingpressed inwardly and the other outwardly. These grooves constitute aroller-race in which are arranged rollers 6, which may be eitherspherical or cylindrical. By this construction the outer wall of thetube and the inner wall of the sleeve are separated one from the other,as shown in Fig. 3, thus permitting a free axial movement of the hoodwith respect to the tube. Furthermore, this form of construction makes amuch better working joint, as the centers of the rollers are brought inline with the space between the sleeve and the tube, making a flexibleand much easier working joint. Any means may be provided for swingingthe hood; but those shown in the accompanying drawings are preferred andconsist of ropes 7, passing over sheaves 8, supported in brackets 9,secured to the outer end of the tube and having their extreme outer endssecured to a lug or arm 10, secured to the lower side of the sleeve.When it is desired to swing the hood to the right, the righthand rope isoperated, and when it is desired to swing it to the left the left-handrope is operated.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, operation, and advantages of myinvention will be readily understood without requiring an extendedexplanation. It is apparent that the parts will not bind eventhough thesleeve should be dented or the tube a'nd the sleeve become rusted,inasmuch as the sleeve is separated from the tube by theroller-bearings. The stacker-tube re ferred to may be of any well knownor approved design, and so may also the hood.

Having thus fully described my invention,

what is claimed as new, and desired to be secured by Letters Patent, is.

1. In a pneumatic straw-stacker, the combigroove of the tube extendinginside of its circumference, the Walls of the groove-being of uniformthickness with the walls of the tube and sleeve, balls in said grooves,the centers of said balls being in line with the space between thesleeve and the tube, and means for revolving the sleeve and hood aboutthe tube, substantially as set forth.

2. Ina pneumatic straw-stacker, the combination with the stacker-tubeand the sleeve mounted to rotate thereon, the sleeve and the tube havingannular coinciding grooves, rollers in said grooves, the groove of thesleeve extending outside of its circumference and the grooveof the tubeextending inside of its circumference, whereby the centers of therollers are brought in line with the space between the sleeve and thetube, substantially as set forth. a

In testimony whereof I have hereunto set 35 my hand in presence of twosubscribing witnesses. s
